P values for vglm(zibinomial) function in VGAM
Hi , I know this question has been asked twice in the past but to my knowldege, it still hasn't been solved. I am doing a zero inflated binomial model using the VGAM package, I need to obtain p values for my Tvalues in the vglm output. code is as follows > mod2=vglm(dmat~Season+Diel+Tidal.phase+Tidal.cycle,zibinomial, data=mp1) > summary(mod2) Call: vglm(formula = dmat ~ Season + Diel + Tidal.phase + Tidal.cycle, family = zibinomial, data = mp1) Pearson Residuals: Min 1Q Median 3Q Max logit(phi) -3.6496 0.273679 0.285619 0.296763 1.0...

Plotting tidal speed and direction in R
Hi, I have had a look around the forums and I can't seem to find anything that works with my data. I have lats, longs, time, tidal speed and direction and need to plot this in an xy plot to determine changes over time. contour and cloud have been recommended to me as a way to do this but I can't figure out how to get 5 dimensions into this. I want lat and long as my x and y, time as my z, direction as w and speed as diffe...

Tidal Time Series Analysis in R
I am looking at using R to analyze time series data containing a tidal component. I need to remove the tidal signal to extract the time series of the phenomena I seek to study. A browse of R-project search engines has not been too fruitful? I've found 'hoa' and 'Rwave', but need further help getting started. THANKS. -wa

RCMD for Windows
Trying to use rcmd in our Windows environment to launch tasks on remote servers. We are using the job scheduler from Tidal corporation. The problem is the return code that's coming back to the job scheduler,Tidal, is from the RCMD NOT from the tasks that it launched. We need to get the return code from the task that was launched via rcmd. Help Lou Zollo Production Control Manager Lava Trading, Inc. 9...

low pass filter analysis in R
Hello R users, I am trying to use R to do the low pass filter analysis for the tidal data. I am a novice in R and so far been doing only simple stuffs on R. I found a package called signal but couldn't find the proper tutorial for the low pass filter. Could anyone point me to the proper tutorial or starting point on how to do low pass filter analysis in R ? Thank you so much....

how to make read-only data frames?
QUESTION: is there a way to make objects (e.g. data frames) read-only? BACKGROUND: I am writing some functions that use a data frame (frequencies of tidal constituents) that I want to be read-only. I can see how to accomplish this within a single function (just define the data in the function), but I'm not sure how to share read-only values between (un-nested) functions. Is there a more elegant method than duplicating the creation of the data f...

Stuck with FFT
Dear all, Before I can get into serious Fourier analysis of Radon time-series I am practising with 24hour and 24.8hour sinusoids to assist with my interpretation of signals ittributed to tidal input to Radon time series. I am stuck. I have tried researching this to no avail. I am awating a book that should describe fourier transforms in detail and another one that should discuss the R application. I know what the command line is but I can't get it to refer to the array. What is ...

post hoc testing of glmer in lme4
I have a mixed model with a binomial response, four factor variables and one random factor. m1=glmer(nbhf.hour~Season+Diel+Tidal.phase+Tidal.cycle+(1|POD.ID),family=binomial,data =bl1,control=list(msVerbose=TRUE)) I have really need to try and find a post hoc test for this model and finding the pariwise comparisons, note the dataset is unbalanced. I had read many questions on this and there doesn't seem to be an accepta...

Principal component / EOF analysis of data dominated by a couple frequencies
Hi R folk, I have a time series of scalar downstream velocity data measured across a tidal channel. The variables are the locations in bins across the channel, the samples are over time. The fluctuation over the tide cycle is an enormous fraction of the time variation in the data ... 96%. The spectral energy of the tide is concentrated in a couple bands that make up the major constituen...

GLS - Plotting Graphs with 95% conf interval
...trying to plot the original data with the line of the model using the predict function. I want to add SE to the graph, but not sure how to get them out as the predict function for gls does not appear to allow for SE=TRUE argument.

Hello, I write a commercial marine navigation and tidal current prediction application for Windows 3.1 (compiled with Borland c++ 3.1). I am considering releasing this or a variant of this under something like Linux. My goal is to continue to develop bells and whistles but to share the load with others. No particular commercial goals. In order to get r...

Urgent - I really need some help lme4 model avg Estimates
...was as follows: "A second model including these variables and wind speed reported a DAICc score <2; therefore, we model- averaged the parameter estimates included in these 2 best models (Table 3). Of the 5 habitats in which we observed plovers feeding, effect size was highest at artificial tidal ponds (5.52), followed by the intertidal zone (3.97). Positive effects of ephemeral pools (2.65) and bay shores (2.32) on adult foraging rates were 48% and 42% lower than artificial ponds, respectively. Conversely, sand flats (-2.30) had an equal but opposite effect on foraging rate, when compared...

A Short Policy Proposal Regarding Host Compilers
Based on my reading of the release pages (https://gcc.gnu.org/releases.html and http://releases.llvm.org/) 6/5 would make GCC 4.7 and Clang 3.1 required, and GCC 4.8 and Clang 3.3 the first to not warn. 6/5 is surprisingly close to making the policy conform to exactly our current time-lag, where we are GCC4.8 (instead of 4.7) and Clang 3.1 (also 3.1). -Erich From: Andrew Kelley
